I am 31 years old and all my teeth except three molars are in good shape. My left lower molar needed a filling where my dentist put in a composite filling. The next day I could not eat the pain was horrible. I went to see another dentist ( mine wasn't open on Sat.)and he performed the cold test which literally made me cry. He gave me pain meds and antibiotics saying there was a very small infection and that she had drilled to the pulp. One week later my dentist put in a temporary filling which she stated was the kind where my tooth would either need root canal treatment or extraction. I no longer felt pain after this. However last week I felt a rough spot on the side of the tooth and could not floss between the back two teeth. Two days ago she said she could not file it because there was a chip on my tooth and the filling was starting to come out. She then gave me a second temporary filling. My pain is back twofold. I can not chew on that side, and immediately after and still my lower cheek feels bruised and sore to the touch. My dentist said she would perform a root canal in a month while working on other teeth which I received another filling with no pain. However I just can't take the pain and would rather the tooth be pulled I cannot take a "failed" root canal. I have read that if the nerve is alive you should not have a root canal and I can't understand why she is waiting so long to pull this tooth. I have been off antibiotics for weeks and I'm very scared of infection.
